Answer 1

In a chemical reaction, the law of conservation of mass states that mass is neither created nor destroyed. Therefore, the mass of the products must equal the mass of the reactants.

Given that two molecules with a total mass of 76 amu react to form a single molecule, the mass of the resulting molecule will be:

76 amu

So the correct answer is:

76 amu
